  • Patent number: 9303957
    Abstract: A roller assembly for applying force to the ground is disclosed. The assembly includes a body adapted to be mounted to a vehicle for moving the assembly, and supports including a first support member supporting a plurality of rollers for applying force to the ground, and a respective piston connected to each roller, the rollers connected via a respective pressure chamber to the corresponding first support member to resist movement of the pistons towards the first support member. The first support member pivotably connected to the body via a first axis such that pivoting movement of the first support member about the first axis as a result of a first torque about an axis has a component about an axis transverse to the direction of travel such that engagement of the rollers with the ground causes a second torque on the first support member opposing the first torque.

  • Patent number: 9279644
    Abstract: A vehicle (2) comprising a vehicle body (6) is disclosed. First struts (16) are mounted to the vehicle body for supporting transport wheels (12) for supporting the vehicle body in a first mode of operation of the vehicle, and second struts (26) are mounted to the vehicle body for supporting roller assemblies (14) for supporting the vehicle body and applying pressure to the ground to detonate explosive devices in a second mode of operation of the vehicle. The transport wheels engage the ground and the rollers are out of engagement with the ground in the first mode, and the rollers engage the ground and the transport wheels are out of engagement with the ground in the second mode. Rollers of one roller assembly partly protrude into gaps between rollers of the other roller assembly.
